Even in unsaturated conditions, longer queues indicate longer travel delays and higher fuel consumption. With the exception of some expensive surveillance equipment, the queue length itself cannot be measured directly. Many methods that estimate the queue length from detector measurements are used in engineering practice, ranging from simple to elaborate ones. The proposed method is based on Gaussian process (GP) model of the occupancy-queue relationship. It can handle data uncertainties and provides more information about the quality of the queue length prediction.
